Title: Semiconductor device
Inventor: SATOU NAOSHI
IPC: H01L29/43
Filed: 1985-07-22
Abstract: PURPOSE:To enhance the reliability of the titled device by preventing the reaction of both of the followings by providing an Mo or W barrier between a III-V group compound semiconductor crystal of GaAlAs, InGaAsP series or the like and a solder of Au or Au-Sn, In-Sn, or Pb-Sn series. CONSTITUTION:A P type InP 5 and P type InGaAsP 6 are laminated on an InGaAsP active layer 3 filled with a P type InP 2 on an N-InP substrate 1, and an electrode window is provided in an SiO2film 7. Next, Cr of about 150-500Angstrom , Mo or W of about 1,000-2,000Angstrom , and Au of 1,000-10,000Angstrom  are laminated by successive evaporation. Loading to a heat radiator produces the electrode structure of ohmic electrode and adhesion layer-barrier metallic laser-Au or solder layer. Even under high temperature and high output, the reaction of the solder and the laser constituent or the rise in operating current due to the diffusion of solder into the laser element never occurs.

Title: Generating circuit of phase modulated wave
Inventor: SHINOHARA HIROSHI
IPC: H03C3/38
Filed: 1982-09-14
Abstract: PURPOSE:To improve automatically the phase linearity, by synthesizing the vectors of a phase modulated wave, obtaining a characteristic compensating signal having an opposite phase to a modulated signal from the synthetic signal and a differential output signal and superposing the characteristic compensating signal on the modulated signal to supply them to a modulating means. CONSTITUTION:A differential output signal sent from a phase shifter 2 is modulated with balance by a circuit 3 and then supplied to vector synthesizing circuits 5 and 6. This differential output signal is synthesized with an output signal Vc, and double- phase phase modulated waves pm1 and pm2 are delivered to the output sides of circuits 5 and 6. This modulated wave is turned into desired phase modulated waves PM1 and PM2 after receiving an amplitude limit and then converted into amplitude modulated waves after receiving the vector synthesization through a circuit 11. Amplitude limiters 13 and 14 have inverting functions and deliver signals having phases opposite to each other to the output side. The signals +mVs' and -mVs' are obtained after the vector synthesization carried out a synthesizing circuit 15. Then signals +Vs and -Vs are detected with mixing by a mixing/detecting device 16 to obtain a characteristic compensating signal VD. This signal VD is inverted with superposition in opposite phase and supplied to a balanced modulator 3 via a modulation amplifier 18. In such a way, the phase linearity is automatically improved.
